To all whom it may concern:

Be it known that I, ANTON KoLAssA, a subject of the Emperor ofAustria-Hungary, residing in Vienna, AustriaI-Iungary, have invented anImprovement in Spacing-Wachines, of which the following is aspecification.

The object is to provide a machine of the nature stated embodying suchcharacteristies that after the workpiece has been positioned in themachine the same may be accurately drilled, punched or stamped inaccordance with predetermined spacing points for the drilling, punchingor stamping operations.

Two forms of this invention are illustrated by way of examples in theaccompanying drawings in which:-

Figure 1 is a front elevation, Fig. 2 is a plan, and Fig. 3 is an endelevation partly in vertical section of one form of the apparatus. Fig.4 is a partial plan of the apparatus, showing a plate fixed in positionfor treatment. Fig. 5 is a front elevation,

Fig. 6 is a plan, and Fig. 7 is an end elevation partly in verticalsection, of a modified form of the apparatus. Figs. 8 to 11 are enlargedviews of certain details.

Referring first to Figs. 1 to 3, 1 is the framing for supporting the bed2 formed with grooves 8 or similar guides in which a table 4 is adaptedto slide longitudinally of the machine. The table 4 carries in bearings5 a rope pulley 8 operated by means of a handwheel 6 on a shaft 7. Anendless rope 9 is wound around the pulley 8 and over guide rollers 10mounted in brackets attached to the bed 2. In a bearing 11 on one sideof the table 4, there is rotatably mounted a hand lever 12 formed with aslot- ]ike recess 13 (Figs. 8 and 9) engaging pins 14 carried by movablestops 16 which can be slid along and adjusted on a bar 15 for thepurpose of holding the table in a determined position. The bar 15 isclamped in brackets 17. In cases where a large number of stops arerequired for a work piece of great length and one bar would not besufliciently long for the purpose, two or more'bars are used, which arebutt-jointed and supported in brackets 18 capable of being slid alongthe bed 2. The stops 16 are adjusted in position on the work-piece whenthe latter isremoved from the workt'able by the operator. 'Theadjustment of the stops when once made for a whole series of work piecescan be easily checked by the shop foreman, so as to insure the perfectaccuracy of the whole of the work. The stops are then finally fixed inposition on the bar 15 by means of bolts or the like. A vise-likeclamping device 19 is provided on the other side of the table 4 forholding the work piece to be drilled or punched. The work piece 20,shown for example, as an angle bar is placed upon grooved rollers 21, asuitable number of which are mounted in side brackets on the bed 2.These rollers are capable of side-wise adjustment to suit the width ofthe angle. The two rollers nearest the tool take the pressure exerted bythe latter upon the work piece. Lateral shifting of the work pieceacross the bed of the machine is prevented partly by rollers 22, andpartly by rollers 23. The rollers 28 are mounted on the ends of aU-shaped bar 24 which is adapted to turn in bearings in brackets fixedto the bed of the machine. A counterweight 26 or the like, carried by anarm 25 of the bar 24, has a tendency to force the rollers 23 against thedepending limb of the angle 20 and thus keep the latter pressed againstthe rollers 23. The rollers 22 and 23 are capable of being adjusted andset to the width or thickness of the workpiece in its transversedirection. As will be noted upon reference to Fig. 2, each roller 22 iscarried by a vertical shaft 22 passing through a lug 22 having a slot 22therein. The shaft 22 is capable of being moved in the slot 22 toward oraway from the ma chine bed, so that in this manner the rollers 22 may beadjusted in relation to the material being operated on. After the stops16 have been set to the desired spacing, and the work-piece has beenfixed to the table 4, the handwheel 6 (or it may be a power drivenpulley) is operated to turn the rope pulley 8 so as to cause the table 4with the lever 12 connected thereto to move along the bed 2 until thelever 12 is brought with its slot 13 over the next pin 14 of the stops16. At the same time the lever 12 is moved down on to the stop 16 insuch a manner that the pin 14 enters the slot 13 and thus prevents thefurther movement of the table. By this movement and fixing of the tableby the lever 12 and pin 14, the work-piece 20 has now been brought tothe working point determined by the spacing and it can now be drilled orpunched. After the drilling or punching at this point, the lever 12 isturned up, and the table 4 is moved farther on until the lever meets thepin 14 of the next stop 16. Then the lever is turned down so that itsslot 13 engages the said pin 14 whereby the movement of the table 4 isagain lim ited in accordance with the spacing, and the work piece 20 hasbeen shifted to the work ing point determined by the spacing. Theseoperations are repeated until the last stop has been reached. In orderto drill or punch other work-pieces according to the same spacing asbefore, it is merely sufiicient to fix the next work-piece in themachine without altering the positions of the adjusted stops 16 on thebar 15. The stops 16 are provided on their upper sides with the pins 14,and on their lower sides with pins 27 which are situated exactly underthe top pins. These pins 27 serve to enable the foreman to adjust stopson a second or third bar away from the table for the purpose ofobtaining a general idea of the distribution of the holes of the severalrows of rivets in the entire work-piece. The construction of the stops16 with pins 14 and 27 has the advantage that the whole bar with thestops can be turned, without having to turn the heavy work piece.

Figs. 10 and 11 show another construction of the stops 16 in which stopfaces 28 are employed against which the levers 12 (formed without slotsin this case) strike.

In the construction of the improved apparatus shown in Figs. 5, 6 and 7,the work piece is stationary, and the drilling, punching or othermachine is arranged to slide in longitudinal guide grooves or the likein the bed of the apparatus, but the adjustment of the machine by meansof a lever connected thereto and the adjusted stops on a bar fixed inthe said bed, is effected similarly to the manner employed in theconstruction just described. The machine 29 (shown as a drillingmachine) is provided with a hand or power driven rope pulley 80 aroundwhich a rope 31 is coiled that runs over guide pulleys 32. The exactadjustment of the working point of the machine 22) is insured by meansof the lever 12 which is pivoted to the machine 29 and has a slot 13adapted to engage the pins 14 of the stops 16 on the bar 15.

Besides fiat bars, angles and different sections, the improved apparatusis capable of dealing with plates. The plate, to be drilled forinstance, is fixed on a table slidable in the same guide grooves, whichis rigidly but adjustably, connected by means of a rod or the like tothe table that carries the driving mechanism and the adjusting lever. Aconstruction of this kind is shown by way of example in plan in Fig. 4.33 is the rod that connects the table 4 to the table 35 carrying theplate 34 fixed on it. The plate runs on the rollers 22 which arearranged on the bed 2 on a level with the top of the table 35.

In practice it is simply necessary for the operator to have theworkpiece in place in the machine and to adjust the stops 14 accordingto the workshop plan and then start the machine to drill, punch or stampthe workpiece.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be per formed, I declarethat what I claim is 1. In a machine of the character described, thecombination of a frame having a bed plate, of a carriage slidable on thebed plate, brackets projecting from one side of the frame, a barremovably mounted in said brackets, upper and lower pins adjustablymounted on said bar, and means supported by the carriage forstep-by-step engagement with one set of the pins to hold the carriage inadjusted position.
